Selected Motor Milestones During Infancy

Have you ever asked yourself the question "Is my infant behaving normally?" That question may be better phrased as "what is typical for infants that are my baby's age?" As we stated in our introduction on our infant postural studies, the development of postural and locomotor milestones has been well documented. Below, we provide a table of some typical ages at which motor skills emerge. It is important to note the age range over which the emergence of these skills is considered 'typical'. Not every child accomplishes these tasks at the same time. Therefore, knowing the average age is not nearly as important as knowing the typical age range as well as the sequence of these skill developments.
